Get a whistle you need it at signal as you cant yell for long, having surveyor tape and a waterproof sharpie to mark area if you are moving in leave in line of sight leave a a trail and increases chance of someone seeing neon tape. Wrap some duct tape around sharpie.
Rather than carry additional gear, after you have shot your azimuth with your compass, mark a tree with your Ka-BAR as a marker.
No trees?
Use the heel of your boot to mark the ground.
We did this in the USMC.
